Hello everyone, I have studied this ticket. When you throw a car out of the event zone, it ceases to be the object of the event, and accordingly the marker on it ceases to exist, and a new car appears in the event zone instead. If the car that was needed for the plane to arrive was thrown out of the event zone, then another car will appear instead of it and the necessary one will be randomly selected from the list of remaining cars. In fact, I do not understand what your problem is, and what you want to say, what happened to you, about what you are asking for help. You say that you threw away the car and the marker disappeared, but this is normal behavior, judging by what I described above. Definitely need a video that will depict what you want to talk about
